Latest Jupiter Stories
Amateur astronomers observing Jupiter with video cameras for the past three years have observed a trio of collisions between small stellar objects occurring around the planet.
A new analysis of near-infrared images taken by NASA's Cassini orbiter is providing more data about the composition of Saturn's atmosphere.
New Cloud-Based Solution Provides Advanced Integration of Student Information, Gradebook, Learning Management and Analytics Systems for K12 Schools Dallas, TX
Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2.
On August 12, 2013, at 5:25 am PDT, NASA’s Juno spacecraft reached an impressive milestone. The Jupiter-bound mission is halfway to its destination.
There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light.
A team of astronomers from the University of Anitoquia, Medellin, Colombia, have discovered a graveyard of comets.
The Car Accident Lawyers, The Berman Law Group in Florida is now offering Jupiter Island, FL, car accident attorney consultations, so call 1-888-211-2304.
Research has led to a new theory that may explain the complex and differentiated origins of solar systems.
Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth.
Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...
Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...
Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...
Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...
Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
